Hi,
I am trying to open the camera on Jetson TX1 developmen kit via OpenCV and I can compile the code.But when I run it,I got nothing.someone said “OpenCV is not using Gstreamer path and pipeline string is being interpreted as V4L2 device”,but I do not konow how to do it.The code is like that:
#include <stdio.h>
#include <opencv2/opencv.hpp>
using namespace cv;
using namespace std;
int main(int argc, char** argv )
{
VideoCapture cap("nvcamerasrc ! video/x-raw(memory:NVMM),
width=(int)1280, height=(int)720,format=(string)I420, framerate=(fraction)24/1 ! nvvidconv flip-method=2
! video/x-raw, format=(string)BGRx ! videoconvert ! 'video/x-raw, format=(string)BGR' ! appsink"); // open the camera
if(!cap.isOpened()){
// check if we succeeded
return -1;
}
Mat edges;
namedWindow("edges",1);
for(;;)
{
Mat frame;
cap >> frame; // get a new frame from camera
cvtColor(frame, edges, COLOR_BGR2GRAY);
GaussianBlur(edges, edges, Size(7,7), 1.5, 1.5);
Canny(edges, edges, 0, 30, 3);
imshow("edges", edges);
// if(waitKey(30) >= 0) break;
}
return 0;
}
I have got the code from the website：https://devtalk.nvidia.com/default/topic/904949/how-to-get-tx1-camera-in-opencv/
Any suggestion will be appreciated,
Thanks
